a citizen oflthe United States, residing: in

Philadelphia,"Pennsylvania, have invented the Cut-Out Mechanism (beinga division of my applioation filed AprilflO, 1917, Se-

rial 'No'. 161,009), of which the-followingfis a specification.

One object o-fmy inventioni'sto so con- "struct the operating mechanism ofa 'nufiier cut-out that it maybe quickly and positively moved to any of ts positions by means of a "treadlei. the connection between the tre adle or other actuating member and the cut-out valve being likew se of novel construction;

A further object lofithe invention provide novel adjustingfmeans for the opiferating mechanism of? a i-muffier cut out 'pensated'for. 1 p v These objects and other advantageous whereby; any variiitionfin length or. position of the operatingf'rod' 'oi 'chain or difi'erenoe in the lineiof thrust ofthe rod may be comends I attain hereinafter set forth, referf ence being had to the accompa-nying'dr avv ings, in which;
